cooling AUDI Q3 2017 Owner´s Manual

Checking and Filling
on even if the ignition is switched off, which
increases the risk of personal injury.
- Never open the cap on the coolant expan­
sion tank when the engine is warm. The
cooling system is under pressure.
- To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
large cloth when opening.
- Do not remove the engine cover under any
circumstances . This increases the risk of
burns.
- If tests need to be performed with the en­ gine running, there is additional danger due
to moving components (such as the ribbed
belt, alternator and radiator fan) and from
the high-voltage ignition system .
- Do not under any circumstances activate the throttle inadvertently (for example, by hand
from the engine compartment) if the vehi­
cle is stationary but the engine is running
and a gear is engaged. Otherwise, the vehi­
cle will start to move immediately and this
could result in an accident.
- Pay attention to the following warnings list­
ed when work on the fuel system or on the
electrical equipment is required.
- Do not smoke .
- Never work near open flames.
- Always have a working fire extinguisher
nearby
- To reduce the risk of electric shock and in­
jury, never touch the following components when the engine is running or is being start­
ed:
- Ignition cable - Other components in the electronic high-
voltage ignition system
- If you must check or perform work on the
engine while it is running:
- Set the parking brake and place the selec­
tor lever in the P (park) position first .
- Always proceed with extreme caution so that clothing, jewelry or long hair do not
become caught in the radiator fan, fan
belt or other moving components or do
not come into contact with hot compo­
nents . Tie back long hair before beginning
160
work and do not wear clothing that can
hang down into the engine .
- Limit your exposure to exhaust and chemi­
cals to as short a time as possible
c:> ,& .
-All work on the battery or electrical system
in your vehicle can result in injuries, chemi­
cal burns, accidents or burns. Because of
this, all work must be performed
only by an
authorized Audi dealer or authorized Audi
Service Facility .
A WARNING
California Proposition 6S Warning:
- Engine exhaust , some of its constituents,
and certain vehicle components contain or
emit chemicals known to the State of Cali­
fornia to cause cancer and birth defects and
reproductive harm . In addition, certain flu­
ids contained in vehicles and certain prod­
ucts of component wear contain or emit
chemicals known to the State of California
to cause cancer and birth defects or other reproductive harm .
- Battery posts, terminals and related acces ·
sories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harms. Wash hands after handling.
(D Note
When filling fluids, be sure not to mix the flu­ids up. Otherwise severe malfunctions and en­
gine damage will occur .
@I For the sake of the environment
You should regularly check the ground under
your vehicle in order to detect leaks quickly. If
there are visible spots from oil or other fluids, bring your vehicle to an authorized Audi deal ­
er or authorized Audi Service Facility to be
checked .

Check ing and F illing
areas, into open streams or down sewage
drains .
- Recycle used engine oil by taking it to a used
engine oil collection facility in your area, or
contact a service station .
Cooling system
Coolant
The engine coo ling system is filled wi th a mixture
of pur ified w ate r a nd coolan t addit ive at the fa c­
tory . T h is coo lant must not be not changed.
The coolant leve l is monito red throug h the . in­
d icator light~
page 13 . Howeve r, we do re com­
mend occasionally check ing the coo la nt level
manually.
I f you must add coolant, use a m ixt ur e of wa ter
and coolant addit ive. M ixing the coolant additive
with d istilled wate r is recommen ded .
Coolant additive
The coolant additive is made of a nti-freezi ng a nd
corros ion protection agents . Only use the fo llow­
i n g coolant add it ives. These additives may be
mixed w it h each other.
Coolant additive Specification

The amount of coo lant additive that needs to be
mixed wit h wate r depends on the climate where
the vehicle will be operated . If the coolant addi ­
tive percentage is too low, the coolant can freeze
and damage the engine.

- Befo re the start of winter, have your author­

Fac ility check if the coolant additive in you r

vehicle matches t he percentage app ropriate
for the climate . This is especially important
when driving in colder climates.
- If the app ropriate coo lant additive is not
available in an eme rgency, do not add any
other additive. You could damage the en­
gine. If this happens, only use water and re­
store the correct m ixture ratio with t he
specified coo lant add itive as soo n as poss i­
bl e.
- Only ref ill w ith new coolant.
- Radiator sealant must not be mixed with
the coolant.

~ Add coolant mixed in the correct ratio
¢ page 166 up to the upper marking.
~ Make sure that the fluid level rema ins stable.
Add more coolant if necessary.
~ Close the cap securely.
Coolant loss usually indicates there is a leak. Im­
mediately drive your vehicle to an authorized
Audi dealer or authori zed Audi Service Facility
and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheating
and be ing pushed out of the cooling system.
.&, WARNING
The cool ing system is pressu rized and can be­
come very hot. To reduce the r is k of burns
from hot coolant :
- Do not open the coo lant expansion tank cap
when the engine is hot. This increases the risk of burns.
- Stop the engine and allow it to cool.
- Protect your face, hands and arms from es -
caping coolant and steam by covering the
coolant tank cap with a large, thick cloth .
- T urn the coo lant tank cap co unterclo ckwise
slowly and keep light pressu re on the cap .
- T o reduce the risk of burns , do not allow any
antifreeze o r coolant to drip onto the ex­
haust system or hot engine components.
T he ethylene glycol in engine coolant can
catch fire under certain circumstances .
- T he coo lant add itive and the coolant can be
dangerous to your health . For this reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury .
Do not add coolant if the expansion tank is
empty. Air could enter the cooling system and
damage the engine. If this is the case, do not
cont inue driv ing . See an authorized Audi deal -
Check ing and Filling
er or authorized Aud i Service Facility for assis ­
tance .
- Before the start of winter, have your author­
ized Aud i dea ler or a uthorized Audi Serv ice
Facility check if the coolant additive in your
vehicle matches the percentage appropriate
for the climate. This is especially important
when driving in colder climates.
- If the appropr iate coo lant add itive is not
availab le in an emergency, do not add any
other additive . You could damage the en­
gine. If this happens, only use water and re­
store the correct m ixtu re ratio with the
specified coolant add it ive as soo n as poss i­
ble .
- Only refill w ith new coolant.
- Radiator sealant must not be mixed with
the coolant .
Radiator fan
T he radiator fan switches on automatically by it ­
self.
An auxiliary e lectr ic radiator fan switches on and
off depend ing on coolant temperature and other
vehicle operating conditions.
After you switch the engine off, the auxiliary fan c a n continue running for up to 10 m inutes - even
with the ignition off . It can even switch on aga in
later by itself ¢.& , if
- the temperature of the engine coolant rises due
to the heat build-up from the engine in the en­
gine compartment, or
- the engine compartment heats up bec ause the
veh icle is parked in in tense sunlight.
.&, WARNING
--
- To reduce the r isk of personal injury never
touch the radiator fan .
- The auxiliary e lectr ic fan is temperature
controlled and can switch on s uddenly even
when the engine is not runn ing .
- The auxiliary radiator fan sw itches on auto ­
mat ica lly when the eng ine coolant reaches a
certa in temperature and will continue to run
until the coolant temperature d rops .
